Abstract
An apparatus and method for the periodic acquisition of data through the use of sensors and/or electronic interfaces. The apparatus is modular, having a control module and one or more A acquisition modules interconnected with a module bus. The control module provides timing and control information to the acquisition modules, as well as an interface for communication to a host computer. Each acquisition module contains circuitry to make measurements of one or more physical property and convert the measurements into digital values. Temperature, altitude, airspeed, engine speed, gravitational force, pulse width, and voltage are examples of physical values that may be measured. Each acquisition module also contains electronic memory in which the digital values are stored. In operation the control module keeps track of elapsed time and periodically signals the acquisition modules to make readings and store values. When data logging is complete, the system is attached to the host computer and the data stored in each acquisition module is transferred for analysis. Calibration values for correction of sensor gain, offset, linearity, or other factors may be stored in a separate parameter area within each acquisition module's memory. These values can then be used by the host computer to adjust and
